Data is available in both realtime via messaging bus and batch via SFTP so you can learn from your users and engage them.

No middleware

Our core doesn’t rely on legacy solutions and is built for high volume TPS, easy integration of new features, and scale on demand.

Native customer support

Admin gives you and your partner bank a single source of truth with built in analytics & reporting so your team doesn’t have to create it from scratch.
